Ambient air pollution brought by the rapid economic development and industrial production in China has exerted a significant influence on socio-economic activities and public health, especially in the...
Downscaling a global climate model to simulate climate change over the US and the implication on regional and urban air quality
Downscaling a global climate model simulate climate change over the US regional and urban air quality
2014/12/12
Climate change can exacerbate future regional air pollution events by making conditions more favorable to form high levels of ozone. In this study, we use spectral nudging with the Weather Research an...
Deep Investigation of Ultrafine Particles in Urban Air
Ultrafine particles Energy Filtered Transmission Electron Microscope analysis Health effects Urban air Carbonaceous aeroso
2016/3/28
This work describes the results of a study which started in 2007 to investigate the ultrafine particle (UFP) pollution in
the urban area of Rome. The sampling site was located in a street with high d...
Particle number size distributions in urban air before and after volatilisation
Particle number size distributions urban air volatilisation
2010/8/13
Aerosol particle number size distributions (size range 0.003–10 μm) in the urban atmosphere of Augsburg (Germany) were examined with respect to the governing anthropogenic sources and meteorological f...
Correlation between Light Intensity and Ozone Formation for Photochemical Smog in Urban Air of Seoul
Ozone production rate Light intensity Photooxidation Twin smog chambers Urban air
2016/3/29
Urban residents are exposed to high levels of ozone that are produced by photochemical reactions of ambient air in
strong sunlight. The potential for ozone formation of urban air needs to be characte...
Biomass burning and urban air pollution over the Central Mexican Plateau
Biomass burning urban air pollution Central Mexican Plateau
2009/8/7
Observations during the 2006 dry season of highly elevated concentrations of cyanides in the atmosphere above Mexico City (MC) and the surrounding plains demonstrate that biomass burning (BB) signific...

2009/1/9
The operational numerical weather prediction model Lokalmodell LM with 7\,km horizontal resolution was evaluated for forecasting meteorological conditions during observed urban air pollution episodes....
Meteorology applied to urban air pollution problems: concepts from COST 715
Meteorology urban air pollution problems
2008/12/31
The outcome of COST 715 is reviewed from the viewpoint of a potential user who is required to consider urban meteorology within an air pollution assessment. It is shown that descriptive concepts are h...
Sources of organic carbon in fine particulate matter in northern European urban air
organic carbon fine particulate matter northern European urban air
2008/11/24
major fraction of fine particle matter consists of organic carbon (OC) but its origin is still inadequately known. In this study the sources of OC were investigated in the northern European urban env...
